How to replace the rear crankshaft seal on Buick Century?

To replace the Crankshaft rear oil seal, initial, take the engine Flywheel out, making sure not to nick the Crankshaft sealing surface. Next, use a flat-bladed tool or another relevant tool by inserting through the dust lip at a small angle and pry the Crankshaft rear oil seal out by guide the tool towards the end of the Crankshaft doing the same in multiple times around the seal as needed. Before installing, apply some engine oil to the new Crankshaft rear oil seal and then place it onto the j 346b6 rear main seal installer(J 346B6). This can be done by placing the installer at the back side of the Crankshaft, hand tighten the screws so that the seal is installed squarely. Then install the Crankshaft rear oil seal on the Crankshaft by selecting the wing nut on the j346b6 and tighten until it bottoms out.
